(Ci. 1031-96) This applicationrelates to a machine to be used in the making of time records on acontinuous record surface, such as a paper tape, and is a division ofour prior application, Serial No. .394,- 330, filed May 20, 1941.

An important object of the invention relates to the provision of meansfor diiferentiating certain records, which means in. the preferred formcomprises a device to impress an auxiliary symbol on the record, andautomatic means to render said device alternately operative andinoperative.

Our invention further relates to arrangements and combinations of partswhich will be hereinafter described and more particularly pointed out inthe appended claims.

A preferred form of the invention is shown in the drawings, in whichFig. l is a front elevation of our improved timestamp;

Fig. l-i' is a partial sectional elevation, taken along the line i-i-ilin Fig. 12; and

Fig. 15 is a plan view of a portion of a tape record.

Referring to the drawings, we have shown portions of a time stampcomprising a frame 29 on which a plurality of type wheels W (Fig. 1) arefixed in the shaft 55.

mounted for rotation by any usual driving mech= .anisrn, such as anelectric motor not shown.

A support 22 is provided at the front of the machine to support a papertape T which is supplied from a feed roll 243. The roll 26 is rotatablysupported in the lower front part of the machine as shown in Fig. l andis frictionally retarded by a spring washer 2.5.

' The tape '1 is drawn up from the roll 26 through a slot 2% inthe'support 22, and passes to the left in Fig. 1 under the type wheels Wand type ribbon R (Figs. 2 and 14) and between a corrugated feed roll to(Fig. 1) and a pressor roll 8i. roll 3i is mounted on a lever 32 pivotedat 33 and yieldingly actuated by a spring 36.

The type ribbon R is mounted on the usual ribhon rolls 35 and 3t and anyusual automatic rib hon feed may be provided for intermittentlyadvancing and reversing the ribbon. Parts of a feed reverse mechanismare shown at 3? (Fig. 2).

A portion 22 (Fig. 14) of the tape support 22 is bent upwardly andforwardly to form a guide slot 38 for the tape T and to separate thetape T and ribbon R, except at the impression point where the support 22and its upper portion 22 are both recessed as shown at 22'' and 22 inFig. 14 to permil; the hammer (it to engage the tape T and force thetape. together with the ribbon, upwardly against the type wheels.

The hammer to (Fig. 10) consists of a block of rubber recessed at ii fora purpose to be described, and secured to the outer end of a hammerlever 52 by a clamping plate 63 and screw M.

The lever i2 is loosely pivoted on a hammer shaft 45 (Fig. 2) and isprovided with a segmental slot or recess 36 (Fig. 9) which receives-astud 47 This loose connection of the hammer lever with the shaft 35permits the hammer to be positively operated for a. stamping stroke bythe stud Al, and also prevents rebound of the hammer from interferingwith the feed of the tape on the return movement of the shaft 45. aswill be hereinafter described.

A lever 38 (Fig. 11) is fixed to the shaft 45 and engages a stop 69 atthe end of the stamping movement of the shaft. A spring 50 secured tothe rear end of the lever 45 returns th parts to normal position andsupplies power for the paper feed.

Th shaft 45 is actuated for an impression stroke by a lever '5! (Fig. 8)which is actuated by a plunger 52 forming part of a solenoid-operatedstamping mechanism mounted within a casing 53 (Fig. 1), the detailsthereof forming no part of our present invention. Mechanism suit- Theable for such purposes is disclosed in the prior patent to Watkins, No.2,102,771. The solenoid circuit includes a control switch S (Fig. 2)which may be quite remote from the recorder.

For the purpose of intermittently advancing the paper tape after eachstamping operation, we mount the feed roll 30 on a horizontal shaft 55(Fig. 2) supported in fixed bearings and extending rearward. The shaftis provided at its rear end with a bevel gear 56 (Fig. 2) engaging abevel gear 5'! on a tape feed shaft 58. The shaft 58 is rotatable infixed bearings and has a ratchet 60 (Fig. '7) mounted near the endthereof remote from the bevel gear 51.

A feed lever B I has its hub 62 loosely mounted on the end portion ofthe shaft 58 and held from displacement by a collar 63 A feed pawl 65(Figs; 7 and 8) is mounted on the lever il and is yieldingly pressedagainst the ratchet 60 by a spring 66.

A link 68 connects the lever 6| to an arm 59 fixed on the hammer shaft45. As the shaft. 45 is moved clockwise as indicated by the arrow a inFig. 8 for a stamping stroke, the feed lever BI is withdrawn and thelatch 65 engages a fresh tooth of the ratchet 50. On the return v strokeof the shaft 45 under the tension of the spring 58, the latch 65'engagesthe ratchet and advances the shafts 58 and 55 and the corrugated feedroll 30 for a tape feeding movement.

A yieldingly mounted holding pawl 10 (Fig. 8) prevents reverse movementof the ratchet 60 as the latch 65 is moved rearward. At the end of itsfeeding stroke the latch 55 engages a stop ll (Fig. 8), thus preventingoverfeed and also limiting the anticlockwise movement of the shaft 45.

The machine herein shown is particularly intended for making a record ofthe repeated occurrence of certain events, such as the starting orstopping of a machine or the opening or closing of a door, and it isdesirable to provide some means for easily identifying all of therecords which have the same significance.

We accomplish this result by impressing a special symbol alongside eachalterna 7 time record, and we have provided special me anism foralternately printing and omitting this symbol on V the printed record. Asample of the tape record is shown in Fig. l5, with the special symbol Sappearing alongside each alternate time and date record.

roll shaft 55 and is intermittently advanced with the feedroll by theratchet feeding mechanism previously described.

The amount of feed is so adjusted that every second feeding operationwill bring one of the teeth -8| under the cam projection 80 and thusadvance the member 15 to the operative position shown in Fig. 12, inwhich position the flexible end of the member I5 projects into therecess 4| and transmits the hammer blow through the tape T and ribbon Rto the projection l3, thus impressing the symbol S on the record.

After an impression has been thus made, the next feeding action advancesthe star wheel 82 to the inoperative position shown inFig. 13, in whichposition the projection 80 is received in therecess between adjacentteeth 8|, and the strip 15 is withdrawn from operative position. Whenthe hammer is operated with the strip 15 withdrawn, no symbol 8 isimprinted on the record.

We have thus provided a time recorder which will print successiverecords on a continuous tape and which will automatically advance thetape after each record has been printed. We have also provided a timerecorder by which alternate records may be quickly and easilyidentified. For

illustration, all of the records indicating starting the operation is tobe recorded.

For impressing such a symbol, we provide a I fixed bar 12 (Figs. '1, 12and 14) having a projection 13 at its lower end positioned alongside thetype Wheels W and above an edge portion of the ribbon R. The projection13 presents the symbol S but overlies the recessed end portion 4| of thehammer 40 and the symbol will not be impressed upon the record unless ayieldablemember 15 (Fig. 12) is interposedbetween the hammer 40 and theribbon R.

Having thus described our invention and the advantages thereof, we donot wish to be limited tothe detail herein disclosed, otherwise than asset forth in the claims, but what we claim is:

1. In a recording mechanism having a record sheet, printing devices andmeans to make an impression therefrom on said record sheet, incombination, a supplemental impression device mounted adjacent saidprinting devices, a pressure-transmitting element insertable between aportion of said impressing means and said supplemental impression deviceand rendering said means effective to make an impression from saidsupplemental device, and automatic means. to alternately insert andwithdraw said insertable element.

2. In a recording mechanism having a record sheet, printing devices andmeans to make an impression therefrom on said record sheet, incombination, a supplemental impression device mounted adjacent saidprinting devices, a pressure-transmitting element insertable between aportion of said impressing means and said supple mental impressiondevice and rendering said means effective to make an impression fromsaid supplemental, device, automatic means to feed said record sheetafter each impression thereon,

and a cam associated with said feeding means and effective toalternately insert and withdraw said insertable element on successiveoperations of said feeding means.
